BEWARE of Memory Leak with Shared Variables

Recommended Posts

Hello all,

NI has an open ticket on a known bug in LabVIEW 8.5 with Shared Variables causing memory leaks. Specifically, String type, Network Published (I'm not sure if Single Process has the leak). The problem supposedly does not exist on 8.2, it came with 8.5.

There's talk of this on the NI forums as well, just wanted to mention it here. The advice is:

1) Don't use string type Shared Variables in 8.5

2) If you must use strings to communicate from a target to a host, convert the strings to U8 arrays (and back again).

I've lost a few days of my life due to this bug. The workarounds do appear to fix it.
